TELEGRAPHIC-TAPE PERFORATOR.

Specification of Letters Patent.

Patented Dec.3 ,1912.

Application filed July 30, 1910. Serial No. 574,596.

To all whom it may concern:

Be it known that I, EDWARD E. KLEIN- a citizen of the United States ofAmerica, residing in the borough of Brooklyn, county of Kings, and Stateof New York, have invented a certain new and useful ImprovedTelegraphic-Tape Perforator, of which the following is a specification.

Thisinvention relates to a machine for perforating tapes to be used inthe Delany system operated by the Telepost Company. The representationof a dot on such a tape consists of two perforations in a lineperpendicular to the tape; and a dash is re resented by two perforationsin a line oblique to the tape. There are two punches arranged in a lineperpendicular to the traverse of the tape and when the depressed, twopunch-actuating magnets are energized as is also the tape feed magnet,the tape being fed when the feed magnet is deenergized. There are twokeys to form a dlash. When the first one is operated, one of t e feedmagnet are energized and when the second key is operated the otherpunch-actuating magnet and the 7 energized. When the space key isoperated, the feed magnet only is energized. The two punches,simultaneously operated when a dot key'is depressed, will produce twoperforations in a line perpendicular to the tape after which the tape isfed forward. When the first dash key is operated, one peroration is madeand then the tape feeds; and when the second dash key is operated, thefinal perforation constituting the dash is made and the two dashperforations are therefore in a line oblique to the tape. hen a space,as between words greater than the normal feed of the tape is required,the space key may be more than once depressed.

The foregoing is a general description of the machine and its behaviorand the invention comprises also certain details of arrangementhereinafter set forth.

In the accompanying drawings: Figure 1 is a plan view: Fig. 2, a sectionon the line 2, 2, of Fig. 1: Fig. 3, a section on l3l16\l1118 3, 3, ofFig. 1: Fig. 4, a horizontal section: Fig. 5, a detail view partly insection and partly in elevation on an enlarged scale showing the head inmounted and in brackets upon which the armature levers of the punchmagnets have dot key is punch-actuating magnets and the tape tape feedmagnet arewhich the punches aretheir bearings: Fig. 6, a detail view ofthe tape feed ratchet wheel: Fig. 7, a detail view of a pulley movingwith the ratchet of the tape feed and adapted by means of a belt toactuate the paper drawing reel: Fig. 8, a detail plan view, with thefinger piece removed, of the dot key: Fig. 9, a front elevation thereofwith the finger piece in position: Fig. 10, a diagrammatic view showingthe two punch-actuating magnets, the paper feed magnet and the circuitconnections of the keys: and Fig. 11, a detail view showing a section ofthe perforated tape.

The main frame 1 of the instrument may be composed of a single casting.In a bracket thereon at one side is the tape supply reel 2 and on anadjustable bracket 3 on the opposite side of the frame is the tapedrawing or take-up reel 4;. The shaft of the paper drawing reel carriesa grooved pulley 5 driven by a belt 6 operated from a pulley hereinafterreferred to that moves with the ratchet wheel of the tape feed. Bracket3 is made adjustable by means of a slot and set screws 7, 7, to adjustthe tension of the belt 6. The paper tape 8 to be perforated passesacross the frame 1 under punches 9, 10; thence over a friction paperfeed reel 11 moving with the paper feed ratchet hereinafter describedand having its surface covered with some suitable friction material,such as leather, that will grip upon the tape. Above this wheel 11, andacting to press the tape against it, is a spring-pressed idler wheel 12whose surface is roughened by engraving, cross hatching, or otherwise.After passing between these two wheels, 11, 12, the tape passes to'thewinding up or draw reel 4. The punch head is best seen in Figs. 2 and5.' A block 13 supported upon the upper face of the frame 1 above anopening therein within which and secured to the block is the die plate14 having in it the female members 15, 16, of the punches 9, 10. Thesepunches are guided in apertures in the lower part of the block at thebottom of a well or cavity therein and also at the top in apertures in aplate 17 screwed to. the top of the block. Coiled springs are appliedaround the punches between the bottom of the cavity and collars on thestems of the punches. In the opposite sides of the block are screwadjustable back stops 19, 20 for the respective armature levers 21, 22,of the punch magnets 23, 24, and in the top of the block are screwadjustafi'ord a proper able front stops that limit the punch-actuatingmovement of the levers. These armature levers are of right angularcontour. Their downwardly extending arms carry armature pieces thatcooperate with the electromagnets and their horizontal parts projecttoward each other and over the punches and are each provided with screwad ustable heads 25, 25, that act upon the punches. The punch operatingmagnets 23, 24, are secured to brackets on the under face of the frame 1as is also the tape feed magnet 26 which has an armature lever 27pivoted in.- termediate its end on a hanger on the under face of theframe.

29 is an adjustable stop for this armature lever applied to its outerend and 30 is its reaction spring which tends to carry into engagementwith the ratchet wheel 31 the rocking driving escapement pallet 32pivoted in the inner end of this armature lever. The ratchet wheel isprovided as usual with a spring pressed dog 33 and the operation of thedriving pawl is,'of course, well understood. On the shaft 35 of theratchet wheel, which has its bearings in hangers carried by the frame,is a grooved driving pulley 34 that receives the belt 6 that drives thetape drawing reel 4, and fast on the shaft 35 is the friction driveroller 11. It is preferred that the pulley 34 be loosely mounted on theshaft 35 and connected as indicated more particularly in Figs. 6 and 7with the ratchet wheel 33 by a spring 36 having a turn or two around theshaft and then having one end secured to the pulley and the other to.the ratchet wheel. The spring is so disposed that it is placed undertension each time the ratchet wheel is advanced one tooth by the ratchetdriving lever 27 There is thus provided an' elastic connection thatguards against injury to the tape because of sudden draft thereon if thebelt 6 be unduly tight. Referring now to the diagram (Fig. 10)

it will be seen that when the key marked dot is depressed a circuit thatincludes the source of energy 37 will be closed at one of the two lowercontacts of the key through punch actuating magnet 23 and tape feedmagnet 26; and also a circuit from the front lower contact of the keythrough the punch actuating magnet 24, tape feed magnet 26 and source ofenergy 37. Both punches 9, 10, will therefore be simultaneously actuatedto produce two perforations in a line perpendicular to the tape, Whenthe key rises, the tape is fed by reaction of the armature leverof feedmagnet 26. When dash key 1 is depressed, a circuit is completed throughpunch magnet 24, magnet 26 and source of energy 37 and one only of thepunches is then actuated to produce the initial perforation b (Fig. 11)

of the pair forming a dash, and when key dash 2 is depressed, the otherpunch mag- .and front elevation in as at a in Fig. 1.1.

net 23 is energized as well as the paper feed magnet 26 and thecorresponding punch actuated to produce the final perforation 0constitutingthe ending of the dash reprsented by the two perforations b,0. When the space bar or key is depressed, a circuit that includes themagnet 26 and source .of energy is completed and on the opening of thekey, the paper tape is fed, the punches during this operation beinginoperative. The contact plates for the bottom key contacts, as well asthe key levers and their top stops, are indicated in the drawings andthe wiring is, of course, properly made. It seems unnecessary todescribe these well known or obvious things as the diagram view 10) isentirely suflioient.

The dot key is shown in detail in plan Figs. 8 and 9. The details areunessential and the construction and behavior of the'parts obvious andspecial description appears unnecessary.
